It is vital to know what lies beneath construction projects before any development can begin.

This webinar will look at recent developments in the subsurface laser scanning, multibeam sonar and photogrammetry geo-referenced surveying of voids and their deliverables for structures and geohazards, ROV surveys of flooded voids and structures.

Also covered will be UAV LiDAR surveys of railway, road, river and canal embankments, cuttings, rock faces and heavily vegetated development sites. Areas discussed include the following:

  • Introduction to Geoterra
  • Geospatial engineering – what is it?
  • Subsurface laser scanning and sonar void survey
  • Unmanned aerial vehicle LiDAR, remote operated vehicles and robotics
  • Case studies
  • Broad commercial costs
  • Future innovations.
